Summit Racing Now Offering A Full Lineup Of Rocker Arms From PRW

New from Summit – they are now offering the full lineup of rocker arms from PRW. These range from stamped steel roller tip rockers to full-bore shaft rockers to meet the needs of your engine. See more details below.

Official Release:

PRW Industries makes lots of performance parts, but we think the company’s rocker arms are worth a closer look. From stamped steel roller tip rockers to full-bore shaft rockers, PRW has you covered.

Sportsman Steel Roller Tip Rocker Arms
PRW Sportsman stud-mount roller tip rocker arms feature 4340 chromoly steel rocker bodies with a longer pivot slot to handle higher lift camshafts, and won’t flex like stamped steel rockers do. The roller tip minimizes valve stem scrubbing to reduce friction. That can free up an additional 15 to 30 horsepower over stock models. Other features include heat-treated pivot balls and RockerLoc locking nuts. Available for small and big block Chevy; small block and big block Ford; Ford 351C; AMC 304-401; Olds 260-455; and Pontiac 265-455.

Pro Series Billet Aluminum Rocker Arms
CNC-machined from 6061-T6 aluminum, these stud-mount rockers can accommodate larger springs and retainers and have full-cage needle bearings to reduce power-robbing friction. Other features include heat-treated roller tips and shaft, internal oiling for longer life, and RockerLoc locking nuts. The pedestal-mount rocker arms for 1978-95 Ford 5.0L and 5.8L engines have an adjustable pedestal to help prevent side-to-side movement at the rocker tip. Available for small and big block Chevy; small block and big block Ford; Ford 351C; Olds 260-455; and Pontiac 265-455.

Pro Series Stainless Steel Rocker Arms
These rocker arms are manufactured from strong, lightweight stainless steel for excellent fatigue resistance and won’t deflect so valve timing stays rock-solid. Other features include full-cage needle bearings for reduced friction; extra-large trunnions to spread out load and reduce wear; heat-treated steel roller tips and shafts and minimize valve stem scrubbing; CNC-machined pushrod cups; and RockerLoc locking nuts. Available for small and big block Chevy; Chevy 348-409; GM LS; small block and big block Ford; Ford 351C; Olds 260-455; and Pontiac 265-455.

PQx Platinum Series Shaft-Mount Rocker Arms
These PQx shaft-mount rocker arms deliver rock-solid valve timing with virtually no flex or deflection. They feature full roller extruded aluminum or stainless steel rocker arms; CNC-machined billet steel pedestals; steel alloy rocker shafts; adjustable cup-style pushrod adjusters; and alloy steel fasteners, studs, and bolts. Available for GM LS, Ford FE, small block Mopar, and big block Mopar.

OEM Upgrade Rocker Arms for GM LS
Designed as drop-in systems to replace your factory rockers, these 1.7 ratio rockers feature drawn cup needle roller trunnion bearings. They’re available in versions with offset intake rockers and straight intake rockers.

Features:

  • Roller tip minimizes valve stem scrubbing to reduce friction
